PDF problems - Windows only - URGENT

[Jonathan Mao <jon@xxxxxxxxxxxxxxxxxxxx>]

Hi

We're a small web development company that has just taken over 
maintenance and hosting of a site. The site used to be on a Wintel 
machine running IIS, it's now with us on Mac OS X running iTools 7.2

Background
------------------
The problem we're having is that some of the PDFs aren't able to be 
viewed by some visitors to the site. Specifically, the problem appears 
to be with Windows users running Internet Explorer v6. The Mac users 
we've tested with don't have any problems viewing any of the PDFs on 
the site.

However, there's no consistency to the problem. In other words, some 
PDFs can be viewed by some users and not others, making it hard to 
isolate the cause of the problem.

For example:
 http://www.commsatwork.org/FDCNews.html
- click on the "March 2004" link

We've had errors from the file being totally blank, to another message 
that says "it does not begin with %PDF" - which is not true. They do 
begin with "%PDF" and I can open all of them on my Mac running Mac OS X 
10.3.3 with Adobe Reader 6.0

Notes
---------
* All the PDFs work with IE 5 - 5.5 with any version of Acrobat from 4 
- 6. It's only IE 6 that the problem occurs.

*** The previous hosting environment was running IIS, our web server is 
Mac OS X running iTools 7.2 ****

I've told the customer that it is highly unlikely that it is a problem 
with the web server. We host many other sites that have PDFs and none 
of these have problems.

------------------
In my attempts to isolate the cause of the problem, I created a test 
page and then asked subscribers to the MacManagers list to see if the 
could open the PDFs.

The results of the test are here:
http://www.commsatwork.org/pdf_test/pdf_test_results.htm

I've checked the MIME settings and it appears to be set up correctly. 
In other worrds, ".pdf" is set to "application/pdf"


*** Question ***
Is there somewhere else I need to check?

Is it possible that iTools is, somehow, not updating the relevant file 
in Apache correctly?

Any other ideas on how to fix this?

From the clients perspective, they're saying that this problem didn't 
occur with the previous host (Windows). So, I'm in danger of losing the 
business if I can't fix the problem.

I'm happy to provide access to a Tenon technician to help get this 
resolved.

I look forward to hearing from you at your soonest convenience.


Yours sincerely

Jonathan Mao
